2014 - 2015 Ford Fiesta ST

 

INSTALLATION TORQUE SPECS 22 in-lbs (2.5N*M) recommended for all worm-gear clamps. These clamps have an operating range of 18-27 in-lbs 2-3N*M. Do not exceed the maximum torque rating of 27 in-lbs (3N*M).

 

 

Give your Fiesta ST the airflow it deserves. The Mishimoto Fiesta ST intake cranks the power up by 6 whp and 10 wtq while running on the stock tune. The mandrel-bent aluminum piping allows for smooth, uninterrupted airflow straight to the turbo inlet hose and into the turbo. The Fiesta ST intake pipe also features a CNC-machined MAF housing that uses the stock MAF sensor, and it includes two CCV ports. The piping is available with either a polished, wrinkle black, or wrinkle red finish to maximize engine bay aesthetics. This Fiesta ST intake also features a black powder-coated airbox to keep the air filter isolated from unwanted engine bay heat. This will help keep your air charge nice and cool, and, like all Mishimoto Fiesta ST parts, this intake comes with the unbeatable Mishimoto Lifetime Warranty!

  • Direct fit for 2014–2015 Ford Fiesta ST
  • Dyno-proven maximum gains of up to 6 whp and 10 wtq on the stock tune
  • Highly aggressive intake tone under acceleration
  • Designed to work with stock tune with no additional tuning required
  • Air filter placed to receive maximum airflow from the front of the vehicle
  • High-flow filter operates at up to 2,000 CFM
  • Black powder-coated airbox keeps unwanted hot air from entering the air filter

FRESH AIR FOR THE FIESTA! ST PERFORMANCE INTAKE R&D, PART 5: PROTOTYPE DYNO TESTING

Dyno preparation for Fiesta ST parts testing
Dyno preparation for Fiesta ST parts testing

Testing day has finally arrived and it’s time to see how our new Fiesta ST parts perform! After weeks of prototype design and fabrication, we have our first prototype Ford Fiesta ST intake system ready for dyno testing. Our first round of product testing is being conducted for two reasons:

First, we want to evaluate power output. Our initial post explained that we were skeptical about making power with our intake. The Fiesta is a MAP-based vehicle and only uses its MAF sensor to gather temperature data. Through our years of development, extracting additional power from speed density (MAP-calculated) is a bit of a challenge. The gains we usually see on these vehicles is a result of reduced restriction within the intake tract. With this intake we’ve certainly improved flow, so let’s see what we are able to produce.

Our second goal with testing is to procure sound clips with our Ford Fiesta ST intake installed. When replacing the restrictive stock setup, intake volume is typically increased, which can be a great added bonus for aftermarket intake installation.

No more waiting, check out the video!

First impressions, this intake sounds fantastic. Noise from the bypass valve is far more audible with our setup installed. Turbo spool sounds are also increased, but not to the point of annoyance. If I was a FIST owner, this would be the blend I’d want for sound improvements.

Next, let’s take a look at the dyno plot we produced with back-to-back testing of the stock Fiesta intake and our prototype.

One thing to keep in mind regarding our testing. Each plot shown is an average of three runs from each setup. We made pulls until the car produced three consistent plots, which were then averaged. To be clear, we did not compare a low run from the stock Ford Fiesta ST intake to a high run from our setup, so this data is completely repeatable.

Our pull starts at 2500 rpm and ends at around 6300 rpm. As you can see, the Mishimoto intake made gains throughout most of the power band, to the tune of around 1-3 whp/wtq on average. Maximum gains of 6 whp and 10 wtq were recorded early on in the pull, at just over 3,000 rpm. Pretty good results, especially considering we did not anticipate huge gains.

As we’ve noted, reduced restriction is the primary contributor to these gains. Our filter has a lot to do with this, made evident by the surface area comparison below.

The stock filter is rather small and we were able to easily improve the size of the filtration area.

Coming Up!

Last series we discussed checking out both intake temperatures as well as the functionality of our additional port on the airbox. The port proved to make negligible differences on the dyno, but we are still interested in seeing if it can contribute to bringing cold air into the box. We will be conducting some additional testing to determine if any changes are needed with our Fiesta ST intake prototype design!

Check out a few shots from the final install.

Everything bolted on perfectly, and this setup looks quite nice in the engine bay of the Fiesta. We will be making one small adjustment to our logo location; in the spot pictured it is a bit hidden by the hood prop rod clip.

Finish Options

Everyone likes to have options; they provide the opportunity to personalize your engine bay setup or match other existing components. We recognize this need, and our team decided on three options for the intake pipe finish. Check it out.

Our three options are polished, wrinkle black, and wrinkle red. The wrinkle finishes are powder coated for optimum scratch and damage resistance.

We highlighted the polished option in detail in our last segment. Check out a couple additional detail shots of the two powder-coated options.

2016 Fitment

As many of you are aware, Ford changed the CCV system on the 2016 model. This adjustment required adding an additional port to our intake piping. Unfortunately, many of the existing 2014–2015 intake systems will not function with 2016 models unless serious modifications are made.

Not to worry though, as our team is working on an adapter that will allow our intake to be used on the brand-new models. Below is a render of our adapter.

This is just a rough design at the moment. We will be working to test functionality and refine the aesthetics a bit.
